Description

Technical Field

[0001] The utility model relates to the technical field of paving chopped yarns, in particular to a sedimentation and paving device for chopped yarns. Background Art

[0002] Chopped yarn is the raw material for producing high-performance carbon fiber products. It is made from high-strength polyacrylonitrile fiber through a spinning process.

[0003] At present, in the production of chopped yarn, it is necessary to flatten the cut chopped yarn so that the chopped yarn can be evenly laid on the processing surface and the surface of the processed chopped yarn product can be uniform. However, when the chopped yarn enters the processing process, the cut chopped yarn enters the sedimentation chamber. On the one hand, some of the chopped yarns will adhere to each other and cannot reach the flat position in time. On the other hand, the chopped yarn will appear granular when falling onto the mesh belt and cannot be evenly distributed on the mesh belt, so that the processed chopped yarn cannot be presented flatly.

The air duct draws air out of the settling chamber when the fan is started, and the upper air damper plate and the lower air damper adjust the air turbulence angle in the settling chamber.

[0011] In a further embodiment, the settling plates are provided with two groups and are respectively located at the upper damper plate and the lower damper plate. The upper damper plate and the lower damper plate break up the chopped yarns in the settling chamber in multiple layers.

[0014] Beneficial effect: The utility model discloses a settling and paving device for chopped yarns. The utility model is provided with two sets of settling plates in the settling chamber. The settling plates drive the chain to rotate through the amplitude modulation motor to adjust the width of the chopped yarns entering the settling chamber. The upper and lower damper plates fine-tune the air flow in the settling plates, so that the chopped yarns falling on the settling plates are disturbed, and then the chopped yarns are scattered. The orifice plate guides the air flow direction of the air inlet, supplements the air volume in the settling chamber, and makes the air volume enter the settling chamber evenly. The upper and lower damper plates are adjusted The angle of the plate is adjusted to break up the chopped yarns from different angles. The bellows collects the floating and sinking particles in the settling chamber under the operation of the fan to prevent them from attaching to the scattered chopped yarns. The sealing rollers on both sides of the exhaust hopper block the air from entering the bottom of the settling chamber to prevent the chopped yarns laid flat on the conveyor belt from being damaged by the fan. The settling chamber has two fans to extract air from the settling chamber, which, together with the symmetrical air ducts and the upper and lower damper plates installed in the air ducts, make it easier for the airflow to break up the chopped yarns, so that the chopped yarns can be laid flat on the conveyor belt more evenly.
